Yes. Works with Quicktime 7.7, but wasn't tested with earlier versions of Quicktime.

Only thing I had to do was change %ProgramFiles% to %ProgramFiles(x86)%. You may want to include some sort of x64 system check which redirects the script to a separate section to copy to that folder instead. You could do a

It copies the same files to the same folders as lvqcl's batch, but uses the unpacked installer (possible with 7Zip) as source. This batch file, the unpacked QuickTime.msi (as folder QuickTime) and AppleApplicationSupport.msi from QuickTimeInstaller.exe have to be in the same folder as qtaacenc.exe.

Convenient, thank you.So basically with QuickTime.msi unpacked to .\QuickTime and AppleApplicationSupport.msi unpacked to .\AppleApplicationSupport in the same dir as qtaacenc and the bacth file, right?

Guys, nao has already and politely asked to keep this thread qtaacenc related, there's a separate one for qaac.

Thanks for pointing this out. Not only will it be appreciated by nao, but it also inspired me to combine several threads about QAAC, including replies by its author nu774; I ask that users keep discussion of QAAC there. Thread:QAAC discussion, questions, feature requests, etc.

You have two options - get an older version of CoreAudioToolbox.dll that was mentioned earlier in this thread, or use qaac.exe instead of qtaacenc.exe because it automatically remaps the channels for the newer versions of quicktime.

buuuut.... i`ve used it for 5.1 dts and ac3 compressions for my personal archive, and I never really seen the error. A fb2k-spectrogram looks like this. Original left, after the break in the middle its the qtaac-output. It looks like everything is in place...

Can please anyone excuse my ignorance and explain what the advantage of keeping the sample rate @ 44.1 KHz when going for bit rates >= 96 Kbps plus low pass is?Anything like unavoidable quality loss during the resampling or generated by buggy code?

There are a lot of variables.

Advantages (+) and disadvantages (-) of keeping 44.1 kHz sample rate:

(+)Time resolution is higher. But it aslo depends of bitrate and encoder. (+) AFAIK Apple's resampler isn't the best around here.(-) You will need more bits to keep the quality.

Apple encoder applies lowpass 15.7 kHz (96 kbps, 44.1 kHz) but it doesn't mean that there is absolutely nothing above that frequency limit.Public test has shown that it's not bad at all to keep native samplerate. Now if it's better or worse on average it depends on a lot of things.
